Abstract
The utility model provides an auxiliary device for ellipticity correcting in large-aperture steel pipeline manufacturing. The auxiliary device comprises an upper half-moon plate and a lower half-moon plate which are vertically arranged in pairs, wherein a lifting jack is installed in the middle of the lower half-moon plate, the lifting jack abuts against the upper half-moon plate through an auxiliary lifting jack circular tube, and the upper half-moon plate and the lower half-moon plate are spliced to be of an integral circular shape. The auxiliary device can resolve the problem of deformation of a large-aperture steel pipeline, and is affordable and convenient to install.
Description
Technical field
The utility model metallic conduit manufacture field, particularly relate to the heavy caliber steel pipe and make ovality rectification servicing unit.
Background technology
In the making of large-diameter pipeline, the major diameter steel pipe often is difficult to control the circular arc degree of pipeline.Because the steel plate thickness of rolling pipeline is generally sheet metal, after moulding, due to the effect of himself gravity, easily distortion, cause the pipeline circular arc degree of rolling inadequate, and on-the-spot pipeline installation exercise difficulty is strengthened.
Therefore, need to make the servicing unit that a kind of steel conduit is controlled its circular arc degree, for solving the problem on deformation of Large-diameter Steel pipeline, facilitate the workman to install.
Summary of the invention
Technical problem to be solved in the utility model is the technical deficiency over against above-mentioned existence, and a kind of problem on deformation that can solve the Large-diameter Steel pipeline is provided, and economic and practical, and heavy caliber steel pipe easy for installation is made ovality and corrected servicing unit.
The utility model solves the technical scheme that its technical problem adopts:
The heavy caliber steel pipe is made ovality and is corrected servicing unit, it is characterized in that: include two meniscus that arrange in pairs up and down, wherein the centre of lower meniscus is equipped with jack, and jack withstands the plate in first half of the month by auxiliary jack pipe, and upper lower meniscus pieces together complete circle.
In such scheme, be provided with pipe, the nested pipe inside that is arranged on of jack in the middle of described lower meniscus;
In such scheme, between described jack and jack pipe, also be provided with backing plate.
Operation principle of the present utility model is: the major diameter steel pipe is after rolling completes, be placed on smooth place, then load onto gusset along circumference one circle electric welding on inside pipe wall, then withstand plate and lower meniscus in first half of the month with jack, first half of the month, plate and lower meniscus withstood gusset simultaneously, respectively to the top of pipeline and below carry out the radian rectification, until pipeline reaches ideal effect, be dismountable this device, this device can be recycled.
The beneficial effect that the utility model can reach is:
This device can solve the problem on deformation of Large-diameter Steel pipeline, and economic and practical, easy for installation.
The accompanying drawing explanation
Fig. 1 is the utility model embodiment device structural representation;
Fig. 2 is the utility model embodiment plate structure in first half of the month schematic diagram;
Fig. 3 is the utility model embodiment lower meniscus structural representation;
In figure: 1. first half of the month plate; 2. lower meniscus; 3. jack; 4. gusset; 5. jack pipe; 6. pipe; 7. backing plate.
The specific embodiment
Below in conjunction with the specific embodiment, the utility model is further described:
Heavy caliber steel pipe is as shown in Figure 1 made ovality and is corrected servicing unit, include two meniscus that arrange in pairs up and down, wherein the centre of lower meniscus 2 is equipped with jack 3, and jack 3 withstands plate 1 in first half of the month by auxiliary jack pipe 5, and upper lower meniscus pieces together complete circle.
In the present embodiment, be provided with pipe 6, nested pipe 6 inside that are arranged on of jack 3 in the middle of lower meniscus as shown in Figure 32;
In the present embodiment, between described jack 3 and jack pipe 5, also be provided with backing plate 7.
Add man-hour, the major diameter steel pipe is after rolling completes, be placed on smooth place, then load onto gusset 4 along circumference one circle electric welding on inside pipe wall, then withstand plate 1 and lower meniscus 2 in first half of the month with jack 3, first half of the month, plate 1 and lower meniscus 2 withstood gusset 4 simultaneously, respectively to the top of pipeline and below carry out the radian rectification, until pipeline reaches ideal effect, be dismountable this device, this device can be recycled.
Protection domain of the present utility model is not limited to the above embodiments, and obviously, those skilled in the art can carry out various changes and distortion and not break away from scope and spirit of the present utility model the utility model.If these changes and distortion belong in the scope of the utility model claim and equivalent technologies thereof, intention of the present utility model also comprises these changes and is out of shape interior.
